warns-seen GUARD.

To all whom it may concern:

Be it known that I, Baron W. MCCLY- MONT, a citizen of the United Statesof America, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inWater-Gage Guards, of which the following is a specification, referencebeing bad therein to the accompanying drawings.

his invention relates to water gage guards, and the primary object of myinvention is to provide an extensible guard which may be increased ordecreased in its longitudinal dimensions to serve as a guard or shieldfor water gages of various 7 lengths.

A further object of my invention is to provide a simple, durable andinexpensive extensible water gage guard that can be easily and quicklyinstalled to prevent pieces of a shattered, burst or otherwise brokenwater gage from injuring engineers, firemen or others in the vicinity ofthe water gage. This is accomplished without materially obstructing theview of the water gage, and the guard otherwise conforms to therequirement of State laws relative to the protection of workmen aboutwater gages.

My invention will be hereinafter more fully described and claimed, andreference will be had to the drawing, wherein- Figure 1 is a sideelevation of the guard as applied to a water gage, showing both partlybroken away;

Fig. 2 is a horizontal sectional view of the guard;

Fig. 3 is an enlarged detail sectional view of extensible arms formingpart of the guard, and r Fig. 4 is a perspective view illustrating amodification of my invention.

As illustrating an installation of the guard there is shown a water gage1 made of-transparent material, as glass, with the ends of the gage orglass tube held in stuffing boxes 2 connecting the ends of the gage towater cocks 3. These elements are of the ordinary and well known typeused in connection with boilers, and it is a well known fact that theglass tubes of such gages often burst and injure workmen adjacent thesame.

The guard which I have devised comprises clamping rings or hands 4adapted Specification of Letters Patent.

Application filcd iuly 24. 1916. Serial No. 110,906.

for embracing the stufiing boxes 2, said bands having clamping screws 5which permit of the bands being clamped upon the stuffing boxes ifoccasion so requires.

Riveted or otherwise connected to one of the bands are the offset ends 6of longitudinally slotted arms 7, and riveted or otherwise connected tothe other of said bands are the ofiset ends 8 of longitudinally slottedarms 9. The arms 7 and 9 are comparatively flat and are equally spacedon the peripheries of the bands 4:, thereby providing intersticesbetween the arms to permit of the gage being readily observed.

The ends of the arms 9 are provided with rivets 10 extending through theslots of the arms 7 and the ends of the arms'7 are provided with rivets11 extending through the slots of the arms 9, the rivets 10 and 11 constituting means for holding the arms 7 in sliding engagement with thearms 9, thus permitting of the longitudinal dimension of the guard beingincreased or decreased for use in connection with gage glasses ofvarious lengths.

The offset ends 6 and 8 of the arms 7 and 9 respectively, place saidarms in proximity to the gage glass and in parallelism therewith andwhile said arms are not of such width as to materially obstruct the viewof the gage glass, yet said arms prevent large pieces of the gage glasswhen broken, from flying outwardly and injurin workmen contiguous to thegage.

he ofiset ends 6 and 8 of the arms 7 and 9 also serve another purposeand this is clearly shown in Fig. 1, where it will be observed that theoffset ends of the arms 9 rest upon the lower stuffing box 2 and therebyrelieve the lower band 4 of stresses and strains due to the weight ofthe guard. In some instances, it may not be necessary to positivelyclamp the band 4 on the stuffing boxes, particularly if there issuflicient friction between the arms 7 and 9 to support the arms 7relative to the arms 9, without clamping the upper band 4 on the upperstuffing box. However, when the guard is used in connection with thewater gages of the boilers of locomotives or other rolling stock, thenit is preferable to fix the upper and lower bands on the gage fittings.

In Fig. 4, there is illustrated a slight modification of my invention,wherein solid arms 12 and 13 have straps 14 retaining said arms insliding engagement, thereby obviating the necessity of slotting the armsand using rivets in connection therewith.

It is thought that the utility of the gage guard will be apparentwithout further description, and while in the drawings there areillustrated the preferred embodiments of my invention, it is to beunderstood that the structural elements are susceptible to suchvariations and modifications as fall within the scope of the appendedclaim.

What I claim is A water gage guard comprising bands, extensible armshavin offset ends c0nnect- 15 ed to said bands an either of the-offsetends of the arms adapted for supporting the guard.

In testimony whereof I afiix my signature in the presence of twowitnesses,
